Is there any plan to contribute to Tree Sitter?

From http://tree-sitter.github.io/tree-sitter/

Tree-sitter is a parser generator tool and an incremental parsing library. It can build a concrete syntax tree for a source file and efficiently update the syntax tree as the source file is edited. Tree-sitter aims to be:

• General enough to parse any programming language
• Fast enough to parse on every keystroke in a text editor
• Robust enough to provide useful results even in the presence of syntax errors
• Dependency-free so that the runtime library (which is written in pure C) can be embedded in any application

The editor has or native support or has a extension that add support:

• Atom: https://github.blog/2018-10-31-atoms-new-parsing-system/
• Neovim: https://neovim.io/roadmap/ - on the next version
• vscode: https://marketplace.visualstudio.com/items?itemName=georgewfraser.vscode-tree-sitter
• emacs: https://github.com/ubolonton/emacs-tree-sitter

And is there an incomplete parser here: https://github.com/tree-sitter/tree-sitter-scala Are there any plans to help on this parse or create your own? It will be one job that could be used by a lot of editors.

Thank you for reporting! I believe tree-sitter is the future for a lot of exciting dev tooling and I would love to have it support Scala. I’m not aware of any ongoing effort to make the current scala support “production ready”, but I want to register myself interested if somebody is working on it.

vscode implemented Semantic Highlight and because of that probably the vscode-tree-sitter will be deprecated https://github.com/georgewfraser/vscode-tree-sitter/issues/30#issuecomment-640270518
